Choose thermally broken steel windows and doors for the best thermal performance available.
We are proud to be the exclusive distributors of the world’s first thermally broken steel window, door, and curtain wall system. Brombal is the only manufacturer who has experience working with thermally broken products since their inception and they have completed many successful projects. Ebe thermally broken sections are bonded together using two materials: the first is a fiberglass reinforced extrusion and the second is a high-density polyurethane resin injected under high pressure. This process firmly joins the frame sections together, ensures a continuous bond, and provides thermal insulation while maximizing structural strength. After years of intense research, the OS2 was born providing narrow sightline, thermally broken window and door systems.
